- Abstract
A new ultrasonic testing method used for the detection of solid rocket motor (SRM) composite shell is proposed, which does not require a coupling agent. The theoretical model of this method is established, and the effect of composite shell thickness, defect size and position on the detection result is studied respectively. The simulation results show that the detection sensitivity decreases with the increase of the shell thickness and the decreases of the defect size, and when the defect is located just in the middle of the transmitting probe and receiving probe, the detection effect is the best.
